Very sad news.
I always enjoyed my chats with Max at various HiFi shows over the years and use two of his TVC pre-amps in my systems, One Loudspeaker I would love to have learned more about is the Sir Galahad. I heard them at the Penta show, must have been early / mid 90s. They were excellent with scale, dynamics and extreme bass extension.
Condolences to his family and friends.
RIP Max
